问题 I wonder is there anyway to select hierarchy in SQL server 2005 and return xml format? I have a database with a lot of data (about 2000 to 3000 records), and i am now using a function in SQL server 2005 to retrieve the data in hierarchy and return an XML but it seems not perfect because it's too slow when there is a lot of data Here is my function Database ID Name Parent Order Function CREATE FUNCTION [dbo].[GetXMLTree] ( @PARENT bigint ) RETURNS XML AS BEGIN RETURN /* value */ (SELECT [ID]

问题 I have a stored procedure which returns a Dataset(Table) . How can I use the result of this stored procedure in a SELECT statement?

Like this: new_ID = ID + 1 Next I drop ID column and rename new_ID to name 'ID'. And how to set Identity on this new column 'ID'?

问题 I've a PK constraint - a clustered index on two columns - which I am in the process of dropping. The command is still running after an hour. I would have thought that as I am just removing a constraint the operation would be nearly instantaneous. Can someone explain to me what is actually happening under the hood when I drop the PK? 回答1: Clustered index is not "just a constraint", it's a storage method. When you drop it, your data are being reordered from clustered storage to heap storage
